Abstract

Monoclinic Zirconia was prepared by basic désintégration of zircon with soda ash. The first step was to break the zirconium silicate down with a thermal treatment at high temperature. Afterwards, an alkaline leaching with soda to eliminate the silica formed during the previous stage was performed. The sodium silicozirconate produced in the thermal treatment was removed with hydrochloric acid leaching
